May I make a suggestion. Separate save and close buttons. Close should not mean save imo. If I chose to look at the seq in the editor and make no changes it should not do a save, update vers, or create a LiveTest seq that needs to be deleted or removed later on close . On the other hand if I make an edit there should be a save.

I do have some work on detecting if a change has been made. This is a carry over from where I had to sacrifice the save button for space. When it only edited the one macro this was easy now I need to do some work.

Need to revisit this properly - moving to 1.4

Using 1.3.3. I don't seem to be able to create a new macro with the in game editor.

launch /gsse
click new
fill in all fields
close sequence editor window with close button  
open /gsse again
new sequence name is not in the list
click 'new' again and my edited content is still in, or prepopulated to, the sequence editor window
/reload wipes temporary edits and sequence window is then empty

Searching GS-Core.lua with an external editor shows no sign of my new sequence.

Turning on debugger, I see "GS-SequenceEditor: No Sequence Icon setting to" when clicking the New button.

Occuring with 1.3.3 Create a 1.3.4
